To all whom it may concern'. y j j ,i i

j Be it known that we, GEORGE H. KELLING- `TON and WALTER A. PREsooTT, citizens-.of the United States, residing at- Decatur, in the j county of Macon and State of Illinois, have invented certain new and useful Improvements in Water-Carbonators,V `of which ,the following is a specification. f

This invention relates to an improvement in water carbonators,and more particularly to that type of device as shown in our co- `pending application Serial Number 7 3,7 44, `filed VJanuary 22,1916, and overV whichthe present structure is an improvement.

An object of our'invention is to Vprovide a device of thecharacter'described which `has the parts thereof so constructedand arranged that the waterand gasare taken into the carbonator through passages opening `at spaced apart points and the gas 1s delivered to exert, impelling.V force upon the water to increase thev head at `which the same .moves, `thereby ,furnishing a motive power sufficient to give the necessarypressure of carbonated water at the Vdraft arm` or other point of discharge. i

- A further object lies inso arranging the parts that the gas inlet port is at all times ,water sealed, and in providing a double valve which controls the supply of both water and gas simultaneously, the valve being so arranged that it is automatically un vseated by the pressure of the iuids thereu yagainst when the pressure withinthe carbonator` is releasedthrough opening ofthe check valve in the draft arm. t Q

With the above and other objects in view .whichwill be in part described.v and in part understood fromthe specification, drawings, and claims, our invention consists in; certain novel features of costruction and combination of parts which will be hereinafter ,more fully set forth.

In' the drawings :--v t y Figure 1 is a view in elevation of a carafter lthe manner of our invention; and, t. j Fig. 2 is a vertical sectional view through the lstructure to disclose the arrangement and mounting of the parts. .j t

. The base block 1 isv enlarged at one end land is bored out to form the water chamber as shown at 2, this enlarged portion of the .base block being externally `screw threaded ammini the open end et thawaterchambcr.

l5. 'rraing an'outletfficm the mining A substantially bell-shaped casing 3 is con-V i structed to be fitted to the base block by being set, upon the external screw threads thereof to provide a mixing chamber 4 into ,-which lthe water chamber opens. The casing 3 has a passage leading therefrom to `provide connection from the mixing chamber4to the draft armfof the fountain, and

1 the `base block 1 has the water inlet passage 46 and the gas inlet passage 7 extending laterally thereinto, nipples formed around the passages and extendingl from the base block being externally` screw threaded to provide for suitable connection to the sources of water and gas supply.

j, The water inlet passage 6 preferably communicates with the waterA chamber 2` substantially at the. side thereof and the gas inlet .passage 7 connects with a gas supply passage' 8, which is arranged to inject the gas into the water chamber substantially at the centerthereofand in a line of flow toward the end of the water chamber opening into the mixing chamber 4.` The bore form- .ing the gas supply passage 8 is continued it is also perhaps desirable that a packing `gland 13 be provided around the stem to 4establish a fluid tight joint. The block 1 is recessed laround thepassage 8 to leave a nipple outstanding with the passage 8 opening therethrough and the inner wall of the recessed formation is internally screw threaded, a sleeve 14 being turned into this screw threaded recess to form a gas chamber through which the gas is conducted previous to discharge into the water chamber 2. This sleeve 14 is made of such length that j. it is` carriedsomewhat below the water inlet `passage 6 and thus even when the check valve of the fountain is closed and the water and gas are held under pressure, the outlet T for'the gas will be water sealed.

t LA hub portion 15 isdisposed at the open endof 4the'water chamber 3 and the pasage c amra eilici'entmixing` is accomplished by more rapid operation of the Tturbine miXer,'-and Jthat the arrangement of .the ,valve structure leaves thegas and` water fvalves on different levels making 'it possible to have the gas inlet port always water sealed. Further, it is apparent that a numberofother advantages are accomplished over-the use of a structure as disclosed in the (zo-.pending application or devices of a similar lnature fcontaind in l the art, Where our improved form of carbon-7T ator is installed.

While We have illustrated and described only one specic form and specific mounting for the invention,vit Will be understood that the position of mounting of the device might be reversed, and it Will further be understood that a number of changes and modications might be resorted to in the form and arrangement of parts Without departing from the spirit and scope of our invention, in View 0f which we Wish to be limited only to such points as may be set forth in the claims.

We claim l. A Water carbonator comprising a casing structure having a Water chamber therein, a mixing chamber Within the casing having communication with the Water chamber, a Water supply to said Water chamber, a gas supply opening in` the Water chamber, and a valve structure mounted to simultaneously close the gas passage and close communication from the Water chamber to the mixing chamber.

2. A Water carbonator comprising a casing structure having a Water chamber therein, a mixing chamber Within the casing having communication with the Water chamber, a Water supply to said water chamber, a gas supply opening in the Water chamber, a valve structure mounted to simultaneously close the gas passage and close communication from the Water chamber to theA mixing chamber, and means located within the mixing chamber to agitate the Water and gas to obtain a proper mixture thereof.

3. A Water carbonator including a casing structure having a Water chamber therein, a mixing chamber Within the casing, a Water supply opening into the Water chamber, a gas supply also opening into the Water chamber, a valve structure constructed and mounted to simultaneously form a closure for the gas passage and to stop communication from the Water chamber to the mixing chamber, means to normally resiliently urge the valve to the closed position, and mixing 4means carried by the valve to be operated by the pressure of air and gas flowing around the valve from the Water chamber to the mixing chamber and to accomplish mixing of the same Within said last mentioned chamber.
